"Overall most of our benchmarks this week of the new Linux
Kernel Page Table Isolation (KPTI) patches coming as a result of the
Meltdown vulnerability have showed minimal impact overall on system
performance. The exceptions have obviously been with workloads having
high kernel interactions like demanding I/O cases and in terms of
real-world impact, databases. But when testing VMs there's been some
minor impact more broadly than bare metal testing and also Wine
performance has been impacted. The latest having been benchmarked is
seeing if the Docker performance has been impacted by the KPTI patches
to see if it's any significant impact since overall the patched system
overhead certainly isn't anything close to how it was initially hyped by
some other media outlets."
